QL30 QL40 QL50 QL60 QL80 Shank DTH button bits for DTH drilling
DTH drilling tool is widely used in underground mining, quarries, hydraulic and Hydro-Power Engineering, water well drilling, Mineral exploration, anchoring hole drilling, geothermal engineering, Subway excavation, another civil engineering. it has the advantage of high flatness, smooth hole wall, high rigid of drill rod and hammer, independent of high axial thrust, no limit of drilling depth, low cost of devices and easiness to maintain. At the drilling hole of dia.105mm-dia.500mm, a plenty of the DTH drilling tools are used.
Features:
1. Button bit is well known for its high wear resistance on medium-hard to hard abrasive rock formations (between 200 Mpa to 260 Mpa compressive strength).Featuring spherical tungsten carbide inserts that is known to have strong configuration against carbide fracture.
2. Recommended for eliminating hole deviation.
3. Widely used drifting and tunneling.
4. Bit face design is ideal for medium-hard to hard abrasive rock.
